The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRAKT

A stroboscope photographic technique was used to investigate the mechanism associated with the disintegration of a conical liquid sheet that is modulated by a piezoelectric driver. The effects of fluid viscosity, driving frequency, and input perturbation power were characterized with respect to the sheet breakup length. The experimental results indicate that the breakup length decreases with increasing input modulation power only at resonant frequencies. This effect is attributed to waves imposed along the liquid sheet surface that amplify wave-mode and rim-mode disintegration, and assist in liquid sheet breakup. The wavelength generated by the modulation was found to depend on the driving frequency and fluid density. The resonant driving frequency is affected slightly by the fluid density. For our experimental arrangement, an optimum driving frequency, for which the liquid breakup length is a minimum, was found to occur at about 10 kHz. Increasing the liquid viscosity impedes the spray development and lengthens the sheet disintegration. Modulation enhances the disintegration of lower-viscosity fluids but is less effective for higher-viscosity fluids. Higher input modulation power enhances disintegration. The relationship between the breakup length and the modulation power is consistent with the analytical solution suggested by Clark and Dombrowski [1] for breakup of an inviscid two-dimensional flat sheet.
